Quantification

In this sandwich ELISA, Pig Tumor necrosis factor (TNF/TNFA/TNFSF2) ELISA kit in the sample is captured between a pre-coated capture antibody and a detection antibody. Signal intensity is proportional to analyte concentration. Quantification uses a standard curve fitted with Curve Expert software, covering 23.5 pg/mL-1500 pg/mL with a minimum detectable dose of 11.75 pg/mL.

For research use only (RUO). Not intended for diagnostic or therapeutic purposes. Validated in pig serum, plasma, cell culture supernates, tissue homogenates matrices only.
Description

This ELISA kit provides quantitative measurement of TNF-α in porcine samples, supporting immunology research where this master pro-inflammatory cytokine drives innate immune activation, sepsis modeling, and tissue inflammation. Because porcine TNF-α levels can shift rapidly from undetectable baseline concentrations to high nanogram ranges during acute immune challenge, the kit is designed to capture this dynamic expression across diverse experimental contexts.

Detection Range: The 23.5–1500 pg/mL range spans the concentrations typically observed in LPS-stimulated porcine whole blood, activated alveolar macrophage supernatants, and serum from experimentally induced endotoxemia, reducing the need for extensive serial dilution in most acute inflammation models.

Alternative Names
TNF; TNFA; TNFSF2; Tumor necrosis factor; Cachectin; TNF-alpha; Tumor necrosis factor ligand superfamily member 2; TNF-a
Function
Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6.; The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.
